A 15 month-monitoring of biofouling in relationship with hydrological parameters and contaminants in three French harbours of the English Channel.

Three French harbours connected to different water masses of the English Channel were chosen to investigate the hydrological parameters, chemical contaminants, and biofouling characteristics for 15 months. The biofouling development on two kinds of coatings, an anticorrosion coating (Epoxy) and a foul-release coating (FRC), was studied to compare micro- and macro- biofouling in harbour environments. Biofouling was investigated by considering wet biofouling biomass and composition, microalgae concentration, and bacterial abundance.

An improved whole life cycle culture protocol for the hydrozoan genetic model .

The jellyfish species (Cnidaria, Hydrozoa) has emerged as a new experimental model animal in the last decade. Favorable characteristics include a fully transparent body suitable for microscopy, daily gamete production and a relatively short life cycle. Furthermore, whole genome sequence assembly and efficient gene editing techniques using CRISPR/Cas9 have opened new possibilities for genetic studies.
